Software-defined architectures are all about decoupling the software from the underlying hardware, meaning you don’t need to buy a proprietary box to use the software’s capabilities. This was the traditional model.
Over time, however, being tied to one provider lost its appeal. A great many software companies started offering many of these bells and whistles that could run on any hardware. Software-defined motion is another step in that direction. One of the earliest forms was software defined storage. The software could run on a variety of vendor hardware or cloud platforms. Following the success of software-defined storage, other similar forms emerged, including software-defined networking.
Here are some of the top trends in Software-Defined Wide Area Networks (SD-WAN):
SD-WANs vs. VPN
SD-WANS decouple the network software from the underlying hardware. This increases flexibility, can reduce costs, and improve scalability, deployment, and…
